"Absolutely. I think that's something I'll continue to do as long as I live - writing for other people," he said.

"As long as I'm, hopefully, writing good quality stuff and people want it, then I'm happy to write for them. It's a great job and something I enjoy."

Asked if he hoped fans of One Direction and Olly Murs - who he has also written for - would get behind him on the talent show, Drewett said: "Hopefully, but I don't want it to be like, 'Everyone get on board'.

"I want it to be fair, because there's a lot of other good acts. If they support me, then great. I want it to be a good competition."

Drewett's co-songwriting credits include 'Best Song Ever' for One Direction, Murs's 'What a Buzz' and 'Dear Darlin'', and The Wanted's 'All Time Low', 'Glad You Came' and 'Lightning'.
